Comedian Raju Shrivastav has received threatening calls warning him not to crack jokes on underworld don Dawood Ibrahim and Pakistan during his shows, police said on Friday.

"Raju Shrivastav was told not to crack jokes on Pakistan. We are investigating to find out the location from where the calls were made," Rakesh Maria, Joint Commissioner of Police, told PTI.

"Initially I thought they were just prank calls. Later, I received some more calls threatening not to crack any jokes against Pakistan," Shrivastav said.

"The person who made phone calls warned Raju that he would lose his life if he continues to crack jokes on Pakistan as well as underworld don Dawood Ibrahim," Shrivastav's business manager Rajesh Sharma said.

Though Raju had not registered a complaint in this regard, crime branch officials approached him and warned him about the threat calls, Shrivastav said.

"Since Thursday security has been provided at my residence and office and I was asked to update the police about my whereabouts," he said.

"In one or two shows, I have cracked some jokes on Pakistan's stand on terrorist Kasab," Shrivastav said adding "it is my work to bring smile on faces of people and I would continue to crack jokes based on real life."
